Hydro Logic Products® AirLift 4XL™ pond aerator and lake aeration systems are designed and built to cost effectively mix and aerate ponds and lakes. Our systems use billions of micron sized bubbles to improve pond and lake water quality. Our AirLift 4XL™ aeration system can aerate ponds and lakes up to 12-acres
in size depending on air diffuser placement, nutrient concentrations, biological oxygen demand (BOD), water depth and other physical characteristics of the waterbody.

Our AirLift 4XL™ lake aerator system is powered by two 1/3 H.P. energy efficient, dual piston air compressors equipped with our proprietary SureStart™ and AirSaver Timer™
technologies. Our dual piston air compressors, which can deliver air under high pressures (water depths up to 35 feet), operates very quietly (55 decibels at 2 meters or 6 feet). In comparison, the noise levels of our air compressors are about 15 decibels less than equivalent rotary vane air compressors.

Our AirLift 4XL™ aeration system contains four AirPod XL™ air diffusers.
The AirPod XL™ contains two self-cleaning 24-inch tubes, EPDM
flexible membrane air diffusers equipped with a triple check valve
system. Our air diffusers are constructed to withstand total airflow from the
compressor without damaging the EPDM membranes (unlike EPDM disc air diffusers). The base of the AirPod XL™ provides a large surface area between the EPDM membranes and the sediments, thereby preventing sediment disturbance during system operation. The AirPod XL™ is extremely easy to install. Simply fill the two ballast tubes with pea gravel or sand prior to their placement in the pond or lake.

Compressed air from our dual piston compressors is delivered to the AirPod XLs™ using our DownUnder™
self-weighted tubing. DownUnder™ air supply tubing is constructed of a flexible PVC composite and is kink proof and puncture resistant. Our easy to install tubing comes in several different lengths and diameters to meet your installation needs.

Our dual piston air compressors are outfitted with our proprietary SureStart™ technology. This allows automatic restart of the air compressors under full pressure during any power outage (blackouts or brownouts) without damaging the air compressor motors. Our AirSaver Timer™ allows the air compressors
to be turned on/off at different time intervals (adjustable up to 10-hours). This provides the pond or lake owner with another option to further reduce the annual operating costs if so desired. The air compressors are oil-less, thermally protected and requires no lubrication. The air compressors include rotors/stators manufactured with the most advanced magnetic materials, sealed heavy-duty precision bearings and starting capacitor. The only required routine maintenance is periodically changing the 5-micron air filters. The compressors can typically operate approximately 3 years or more before any decline in performance is observed. This is 2 to 3 times better performance over standard piston, diaphragm and rotary vane compressors. Thereafter, the air compressors can be easily serviced by replacing the piston seals. Airflow versus pressure performance curves for our dual piston compressors vary less than for diaphragm and rotary vane compressors. This simply means that means that dual piston compressors provides more air while using less energy. Lastly, our dual piston air compressors can operate under high pressures, thereby allowing the air diffuser membranes to be easily cleaned without pulling the AirPod from the pond or lake.

• Manifold equipped with Viton sealed valves to precisely control the airflow to AirPod diffusers

• Heavy duty (24”L x 24”W x 2”H) HDPE mounting pad included

• Overall dimensions (24”L x 24”W x 24.6”H)

• Five-year warranty (best in industry)

The commercial-grade cabinet is constructed of 14-gauge steel with forest green electro-statically bonded powder coating. The cabinet is manufactured with a stamped ventilation intake grill and low resistance exhaust plenum (duct work). The cabinet comes equipped with sealed ball bearing cooling fan to maximize air compressor life and Class “A” GFCI Protection on all circuits. All cabinet components are easily disassembled using standard household tools. The cabinet includes a 5-year warranty against rust and corrosion and a 2-year warranty on all components mounted inside of the cabinet.

Each AirPod XL™ air diffuser contains two self-cleaning 24-inch, EPDM flexible membrane tube diffusers equipped with a triple check valve system. The triple check valve prevents water and sediment from flowing back into the air supply lines during system shut down. The EPDM tube air diffusers are mounted to heavy-duty PVC strut with ratcheting tie-downs to provide easy assembly/disassembly. The above components are secured to a large HDPE base. Two hollow ballast tubes are anchored beneath the base. The ballasts tubes are designed so that pea gravel or sand can be easily added to these tubes during installation.

DownUnder™ Self-weighted Air Supply Tubing

• Over-sized 0.625 inch I.D. for low-pressure drop applications*

• Heavy-duty wall thickness for durability

• Self-weighted for easy installation

• Kink proof & puncture resistant

• Available in 100 ft. (boxed) and 500 ft. (roll) lengths

• 15-year warranty (best in the industry)

* DownUnder™ air supply tubing is also available in 3/8 inch I.D. (0.375 in.) for smaller pond and lake applications

DownUnder™ air supply tubing is constructed of a flexible PVC composite and is self-weighted in order to firmly remain along the pond or lake bottom after the installation. Sections of DownUnder™ tubing are connected together using standard PVC solvent weld cement and ½ inch insert fittings. DownUnder™ air supply tubing has low friction walls (0.625 inch I.D.) for maximizing airflow rates and minimizing air pressure drops. Our DownUnder™ tubing is designed to reduce the overall system pressure requirements and to extend the life of the air compressors. The wall thickness of 0.225 inches provides long-term durability and protection against kinking and punctures. The air supply tubing remains flexible in cold temperatures allowing for easy year-round installations.
